UNDERWOOD, N.D. — Greg Schutte compares Great River Energy's current transmission system to an 8-track tape and the improvements being made as upgrading to the latest iPhone.

The CU HVDC line, which stands for high voltage direct current, was put in service 40 years ago in 1978.

It's an extremely important line to GRE because it moves 73 percent of the cooperative's power supply 436 miles from Underwood to Buffalo, Minn., west of the Twin Cities, and serves about 500,000 customers across Minnesota and parts of Wisconsin.

The power cooperative is preparing to invest $130 million in the line, which Schutte said is imperative to continue producing power at the state's largest coal-fired power plant, Coal Creek Station.
